Title
Magnets And Liquid

Problem Scenario

I wanted to know if a liquid would change how a magnet works.

Broad Question

How do liquids affect a magnet's performance?

Specific Question

Do different liquids effect how well a magnet performs under the liquid?

Hypothesis

A liquid that is less dense will allow the magnet to have more force therefore it can collect more paperclips.

Variables

Independent Variable: Liquid Type

Dependent Variable: Magnet Performance

Variables That Need To Be Controlled: Magnet Type

General Plan

In this experiment, how well a magnet works under water would be put to the test.The magnet will be put under one of the specified liquids. Then paperclips would be put under the liquid with the magnet. After that the magnet will be pulled out of the liquid. The paperclips will be counted and then recorded.

Potential Problems And Solutions

There are a few possible problems to doing this experiment. One is that the liquids could get into someones eyes. Wearing saftey goggles will prevent this. Another potential issues is that if someone swallowed a magnet. The only way to prevent this is to not swallow a magnet

Experimental Design

Number Of Comparison Categories:

There are four categories to be compared.

Number of Comparison Samples:

There will be one comparison sample.

Number Of Observation In Each Sample:

Five observations will be taken for each sample.

When data will be collected

The data will be collected each day thirty seconds after the magnet is placed in the liquid.

Where will data be collected?:

The data will be collected in a lab notebook and transferred to a Wiki after my project is completed.

Resources and Budget Table

Item	Amount Needed	Where I Will Get This	Cost
Magnets	1	My house	$0.00
Isoprophyl Alchohal	100ml
Water	100ml
Vinegar	100ml
Salt Water	100ml

Detailed Procedure

In this experiment there are a few steps to follow. First, a beaker will be filled with one of the four liquids (100 Milliliters). Then a specified amount of paperclips (30) is put into the liquid. The magnet is then placed in the liquid. After approximately thirty seconds pull the magnet out. When that happens count the amount of paper clips and record the data.

Data Analysis

The comparison data showed an average of 8.75 paperclips per trial. The Vinegar was the most tying with another liquid. Vinegar and salt water both picked up 9 paperclips per trial on average. The lowest average was from the isopropyl alcohol which got only 7.7 paperclips per trial. The last liquid was water. Water was equal as the comparison data.

All Raw Data

Paperclips I used

Isopropyl Alcohol used during the expiriment

Vinegar used during testing

Results

The data shows that vinegar was the best along with water. Compared to the test with no liquid, vinegar and water had .5 more paperclips picked up on average. Isopropyl alcohol was the third best with an average of 8 paperclips. Salt water was the worst. It only collected 7.5 paperclips per trial. Liquids had different amounts of paperclips collected proves that liquid affects magnetic effectiveness.

Conclusion

Liquid does affect the effectiveness of a magnet. Although my hypothesis was incorrect, the experiment was successful. Throughout the data it shows that different liquids provide different results. Some are better than the comparative data and others were worse.

Discussion

It's true that liquid effects how well a magnet performs. Different liquids would get better or worse results. Magnets may be needed under a liquid in the future. If we do in the future than this experiment will help decide what liquid to be used to get the most success. This Experiment didn't really have trends. The only issue that occurred during the experiment was how to get the magnet out with out messing up the data. Taking it out with forceps was a solution to this problem.

Background Research

Magnets: A magnet is something with a magnetic field. It attracts pieces of nickel, steel, iron, and cobalt. Magnets are made for different uses. The compass needle is an example. One side of the magnet points towards the northern pole, the other end points south. All living things create a magnetic field. Magnets are made for many different things. The most known reason is the compass. Another is made to be used when doing magnetic therapy. In magnets opposites attract. The North attracts the South but repels itself. It's the opposite for the South. The South attracts the North and repels the South.

Abstract

There is a lot to learn about magnets. They are used for many things and in many way. It was interesting to learn and experiment with. It proves that a liquid does effect how well magnet works. Due to the data showing liquids getting different results it shows that the liquid did effect it.
